The Intermountain Medical Center Heart Institute in Utah studied 5,695 men ages 53-71 who had initial low levels of testosterone (read the study here… ). Only 14% of these men received testosterone replacement to achieve normal to high levels of testosterone. Those who did not take supplemental testosterone remained at low levels for the three years of the study. The 14% who replaced their testosterone to normal or high levels had reduced rates of death and reduced heart attacks or strokes at both one and three years.

According to the FDA there were 1.3 million patients with prescriptions for testosterone in 2010 and 2.3 million in 2013. Men ages 40-64 make up 70% of these patients. My own experience is that we are seeing much greater numbers of men, young and old, who are in desperate need of Testosterone Replacement Therapy (TRT). I suspect it is a result of the huge increase in use of endocrine disrupting chemicals that are now in each of us at increasing levels.

There have been a few recent studies that were casting doubt on the safety of TRT. The bulk of studies support the use of TRT for those who are low and thankfully we have several bio-identical products available to us.
